Summary

WHAT THE DATABSE WAS DESIGNED TO DO. The database was designed to document all of the observations of this mountain beaver and its distribution. HOW THE DATABASE WAS DESIGNED TO BE USED. It was designed to be used with the recovery plan to identify conservation and protection activities to maintain mountain beavers at least in their known habitat.

Description

This data set describes the distribution of 110 observed burrow systems in 26 different local populations. TIME PERIOD COVERED. All sites were first discovered from 1981 through 1997 except for the very first observation of a Point Arena mountain beaver which occurred in 1951. NUMBER OF RECORDS. There are 110 records of different burrow systems presented here. GEOGRAPHIC EXTENT OF THE RECORDS. The records extend from about 0.5 mi south of the town of Point Arena to about 10.5 mi north of the town. Almost all records are within 3 miles of the coast. BASE DATA STRUCTURE. The base data structure is a dBASE 5.7 .dbf file. WHAT EACH RECORD REPRESENTS. Currently each record documents the location of a burrow system and provides the date when the system was first located and when the last observation record was made. The data table has fields for characteristics of the burrow system but they are not used.

Supplemental information
HOW DATA WERE COLLECTED IN THE FIELD. Mountain beaver burrow systems were searched by traversing potential habitat and looking for burrow entrance holes. Survey records came from individuals who had knowledge of the characteristics of mountain beaver burrows. WHO COLLECTED DATA IN THE FIELD. Records here have come from an academic researcher, Department biologists, and contract biological consultants investigating potential project impacts. WHO DID THE INITIAL DATA COMPILATION. Data were compiled by Department staff in the Bird and Mammal Conservation Program. BASIS FOR GEOGRAPHIC COORDINATES. In most cases copies of USGS Quad. maps were carried into the field and when burrow systems were found they were appropriately marked on the maps. These maps were then used to calculate the UTM coordinates (NAD27) for the points using complete Quads. GENERAL ASSUMPTIONS OF THE DATA. * The people whose records appear in this database were sufficiently knowledgeable to determine if a hole, or series of holes in the ground constituted a mountain beaver burrow. * The existence of mountain beaver burrow entrances represented an active or a recently active burrow system. * Repeat visits to a burrow system that showed little degradation of the entrance holes meant the system was active or recently active. * Surveyors could locate themselves on topographic maps with the degree of accuracy noted in the database. KNOWN CAVEATS OF THE DATA. * This is not a complete enumeration of all existing Point Arena mountain beaver burrow systems; not all prospective habitat has been checked for burrow systems. * It is not known for certain if each burrow system was currently occupied at the time that it was located or subsequently revisited.
